Correspondence with a professor in Japan:
I grew up in and around San Francisco where I worked with and developed friendships with people of all sorts of backgrounds, and as a young child I learned that my favorite cousin is gay. As a result, I believe that all love is good love, with the exception of abusive love. I want everyone to be happy and to be able to freely express their love. When I express this in my classes, I notice that some students seem to become more interested in the class or to listen to me more carefully.
In addition to classes general communication classes, I also teach classes related to American culture. I often cover issues related to gender and sexuality, and my students are deeply interested in these topics. I am sure that some of my current students and past students are homosexuals, but none of them have directly expressed it. However, several students have chosen to write about homosexuality in Japan and America for their graduation research paper.
From my own second language learning experiences with French, Thai, and Japanese, I realized that my personality changes according to the language that I use. When I speak Thai, I feel and become very playful. I love that language and completely relax when speaking it. There are concepts that can be expressed in Thai that I cannot easily express in English. With Japanese, I feel reticent and awkward. I dislike the Japanese language. Of course, Japanese also expresses some concepts that are not easily expressed in English. My Japanese wife who studied in America has often stated that there are times when English is much better than Japanese for expressing herself.
I believe that the structure of a language can match or block the psychological expression of a person. Perhaps, the perception of the majority of users of a language can have an effect on the ability to use that language to express oneself. Maybe, Japanese learners of English hold the stereotype that America is a free country. Those people might then be able to more freely express aspects of themselves that they do not openly express in their native language.
If I can help you, I will be happy to do so. If you would like me to take a survey or write answers to questions, etc., feel free to request that. I wish you the best of luck with your research.
